Re: why wont sims 4 stay open

I know you said you tried the most common fixes but just encase.

1) Have you updated Windows

2) Have you updated your graphics drivers.

3) Verify and Repair game files.

4) Check to see if your Mods/CC have been updated and are compatible with the current game updates. Or disable your mods and CC.

Hope some or any of this can help you. Good luck,
